  • Publication number: 20230332140
    Abstract: Described herein are approaches allowing the storing of data at lower densities and increased write speeds. Indexing and recording of data may be separated into separate processes. Rapid DNA extension reactions can then be performed at many distinct locations throughout a solid support, so that the write speed is limited by the ability of the instrumentation to perform spatial addressing operations, rather than chemical synthesis steps.

  • Publication number: 20230264164
    Abstract: Nucleic acid memory strands encoding digital data using a sequence of a homopolymer tracts of repeated nucleotides provides a cheaper and faster alternative to conventional digital DNA storage techniques. The use of homopolymer tracts allows for lower fidelity, high throughput sequencing techniques such as nanopore sequencing to read data encoded in the memory strands. Specialized synthesis techniques allow for synthesis of long memory strands capable of encoding large volumes of data despite the reduced data density afforded by homopolymer tracts as compared to conventional single nucleotide sequences.

  • Publication number: 20230227880
    Abstract: The invention provides improved methods for synthesizing polynucleotides, such as DNA and RNA, using renewable initiators coupled to a solid support. Using the methods of the invention, specific sequences of polynucleotides can be synthesized de novo, base by base, in an aqueous environment, without the use of a nucleic acid template.

  • Patent number: 11390858
    Abstract: The invention includes methods for identifying polymerases, such as modified terminal nucleotidyl transferases (TdT), that are capable of binding nucleotides comprising removable 3?-O-blocking moieties to a nucleic acid initiator, without the use of a template. The invention further includes the identified polymerases, and methods of using the polymerases for de novo synthesis of predetermined oligonucleotide sequences.

  • Publication number: 20210340608
    Abstract: The invention provides improved methods for synthesizing polynucleotides, such as DNA and RNA, using enzymes and specially designed nucleotide analogs. Using the methods of the invention, specific sequences of polynucleotides can be synthesized de novo, base by base, in an aqueous environment, without the use of a nucleic acid template. Because the nucleotide analogs have an unmodified 3? OH, i.e., as found in “natural” deoxyribose and ribose molecules, the analogs result in natural polynucleotides suitable for incorporation into biological systems.

  • Publication number: 20210301337
    Abstract: The invention generally relates to methods for analyzing nucleic acid sequence information. In some aspects, a sample is sequenced to obtain nucleic acid sequence information. In some aspects, an amount of GC bias in sequence information is determined. In some aspects, sequence information is corrected to account for the GC bias. In some aspects, corrected sequence information is analyzed.
